Abstract

Spent Ni-Mo HDS catalyst is one
of the most important secondary resources for the recovery of valuable metals.
Recovery processes are important from the economical and environmental point of
view. Ni content of Ni-Mo HDS catalyst was determined as 5.27 % after oxidative
roasting. Production of NiC₂O₄∙2H₂O
from roasted HDS catalyst was investigated in this work. It is seen from the
ICP-OES analysis that nickel concentration in the solution was increased to a
maximum value at the beginning of the experiment and then decreased. NiC₂O₄∙2H₂O
was formed in a consecutive reaction in two steps. NiC₂O₄∙2H₂O
was produced with efficiency of 99.1 % from the experiment carried out using
1/10 solid/liquid ratio, 40 ^oC temperature, 1 M oxalic acid, 300 rpm
stirring speed and 480 minutes reaction duration. TG-DTA analysis performed in
dry air atmosphere showed that NiC₂O₄∙2H₂O
produced decomposed in two steps and formed NiO after second decomposition step
at about 350 ^oC.

Kullanılmış Ni-Mo Hidrodesülfürizasyon Katalizöründen Nikel Okzalat Dihidrat Üretimi

Abstract

Kullanılmış
Ni-Mo HDS katalizörü, değerli metallerin geri kazanımı için önemli ikincil
kaynaklardan biridir. Geri kazanım prosesleri hem çevresel hem de ekonomik
açıdan önem arzetmektedir. Oksitleyeci kavurma sonrasında Ni-Mo HDS
katalizörünün % 5.27 Ni içerdiği belirlenmiştir. Bu çalışmada oksitleyici
kavurmaya tabi tutulan Ni-Mo HDS katalizöründen okzalik asitli çözeltilerde NiC₂O₄∙2H₂O
üretimi incelenmiştir. ICP-OES analizinden çözeltideki nikel konsantrasyonunun
deneyin başında arttığı, bir maksimum değere ulaştıktan sonra azalmaya
başladığı görülmüştür. NiC₂O₄∙2H₂O’ın iki
adımda konsekütif reaksiyon sonucunda oluştuğu tespit edilmiştir. 1/10
katı/sıvı oranı ile 40 ^oC sıcaklık, 1 M okzalik asit çözeltisi, 300
rpm karıştırma hızı kullanılarak 480 dakika süre ile gerçekleştirilen deney
sonucunda % 99.1 verimle NiC₂O₄∙2H₂O
üretilmiştir. Kuru hava atmosferinde gerçekleştirilen TG-DTA analizi, üretilen
NiC₂O₄∙2H₂O’ın iki kademede bozunduğunu ve 350
^oC civarında tamamlanan ikinci bozunma kademesinden sonra tamamen
NiO’e dönüştüğünü göstermiştir.
